United States Patent 3,235,127 HAND-@PERATED DISPENSER FOR OIL Marion l). Cline, RD. 1, Blairsville, Pa. Filed May 22, 1964, Ser. No. 369,379 3 Claims. (Cl. Z22- 82) This invention pertains to a pumping means particularly adapted for use in association with uid containers, but having features of general adaptability to the pumping of uids.

It has been previously proposed to provide pumping attachments for use with fluid containers, such as lubricant cans, but such prior attachments have failed to iind general acceptance due to diiculty of application to the container, diliculty in operation, cost, and other problems. To overcome these objections in a device of this character, and to supply a new and novel pumping means for use in a canister or the like is a basic objective of the present invention. In accordance with this basic objective, the invention relates to the provision of a combined can holder and dispensing pump arranged to direct Huid discharge from the can through a spout means, the apparatus being readily applied to a can, being non-complex in operation, inexpensive to manufacture, and having a new and novel valve means positively preventing accidental or inadvertent liquid discharge from the pump.

Other and further objects and advantages of the invention will become apparent to those skilled in the art from a consideration of the following specification when read in conjunction with the annexed drawings, in which:

FIGURE 1 is a side elevational view of a pump and holder constructed and assembled in accordance with the teachings of this invention;

FIGURE 2 is a bottom plan View of the apparatus of FlGURE 1;

FIGURE 3 is a top plan view of the apparatus as applied to a container;

FIGURE 4 is a vertical cross sectional view substantially on the line 4-4 of FIGURE 3, with the container partially broken away; and

FIGURE 5 is an enlarged, fragmentary detail sectional view, taken substantially on the section line 5 5 of FIG- URE 4, looking in the direction of the arrows.

Referring to FIGURES 3 and 4 of the drawings, a conventional container such as an oil can lil is therein shown, the can having `a tubular side wall 14, a base and a top 18. The top 1S and base 15 are secured to the side wall 14 by connecting, circumferential rim portions Ztl. This can structure is of course conventional.

For use with containers such as the can 10 shown herein, the present invention provides a holding and dispensing apparatus 22 comprising an outer frame 24 adapted to fit about and engage the can. The frame 24 includes a pair of elongated, upstanding, spaced apart top members 26 and 23, extending across the can top 18 and connected at their forward ends 30 by a forward cross member 32 having an inner end 34 and an outer end 35, the forward cross member being preferably integral with the top members.

Depending from the outer end 36 of the forward cross member 32 is an elongated front brace 38 of arcuate section adapted to bea-r against the side wall 14. The brace has an outwardly struck rim engaging portion 4t) at its upper end, and has an outwardly bent, lower entry end 42. As seen in FIGURE 4, the brace 38 extends substantially the full height of the side wall 14 and its rim engaging portion 4i) is pressed against the can rim 2t) at the upper end.

A rear cross member 44 connects the opposite or rear end portions 46 of the top members 26, 28, and the cross member 44 merges at its outer end with a depending handie member 48. The handle member is generally of channel form, with inwardly crimped fianges 50, and has an arcuate, inwardly projecting portion 52. An elongated, transversely arcuate, back brace element 54 is provided and is integrally connected at its lower end 56 to the inward portion 52. The back brace 54 bears against the container side wall 14 at a location substantially diametrically opposite the brace 38, extends gene-rally the full height of the container, and has an upper end 58 terminating in a rim-engaging lip 60. The lip 60 carries an inwardly projecting arm member 62 with :an upstanding eye member 64, and a similar eye 66 is secured on the inner end 34 of the cross member 32. A coil spring 68 extends between the eye members 64, `66 and exerts a force to pull the rirn engaging portions 40 and 604 of the braces 38 and 54 toward one another to clamp the same about the can 1t).

An elongated, tubular standard '70 is provided and extends through the forward cross member 32. The standard has an inner wall 72, and outer wall 74, and upper and lower end portions '76, 7 8. The lower end portion 78 is slanted to provide a can top piercing end, forced through` the can top as at tt) forcing a section 82 thereof aside. The upper end portion 76 projects outwardly of the can, the inner wall 72 is provided with threads thereat to receive a packing nut 84 with a bore S6 therein. A resilient washer 88 is positioned about the standard over the can opening to provide a seal.

As shown in FIGURE 4, a plunger 90 of elongate, substantially cylindrical form is slidably mounted in the standard 7) and has a lower end portion 92 and upper end portion 94. The lower end portion 92 has a circumferential groove 96 formed therein, providing a generally spherical ball 98 on the extreme end thereof, while the end portion 94 projects outwardly of the standard, through the packing nut 84, and has an opening 100 therein. The ball 98 is provided with a longitudinal passage 98. A shaft 102 extends through the opening 100 and is connected at its ends to links 104 arranged on opposite sides of the standard 70 and spaced from one another by a spacer 1116. Links 104 are pivotally connected to extended `arms 163 of an elongated actuating lever 110 mounted on a pivot axle 112 extending between the top members Zd and 2S adjacent the ends 46 thereof. Manual depression of the outer end 114 of the lever 110 thus serves to raise the plunger 9% inthe standard 7 0.

A valve sleeve 116 of substantially tubular form is slidably mounted in the standard 70 adjacent its lower end 78, land has an upper portion 118 crimped about the groove 96 of the plunger to clamp about the ball 98, and an annular sealing ring 121) extends about the crimped portion. The lower end 122 of the valve sleeve is inwardly crimped at spaced apart locations, to provide laterally extended feet 124 about lan inlet opening 126, and a captive ball 128 is encased therein. A coil spring130 extends between the plunger ball 98 and the captive ball 12S. An elongated coil spring 132 is coiled about the plunger 90 in the standard and presses against the packing nut'Si at one end and against the valve sleeve 116 at its other end, whereby the spring exerts constant bias against the sleeve 116 to press the same against the container bottom 16. Spring 132 returns the plunger to an upwardly projecting position when the end 114 of the lever 110 is not depressed.`

A spout assembly 134 is provided and including a sub- -stantially cylindrical outward member 135 with a compound bore 133 formed therein communicating with the standard 70 and xed thereto integrally or otherwise adjacent the upper end 76 thereof. An elongated spout 140, with a dispensing opening 142 is provided, and has an enlarged end 144 connected about the outward member 136. A ball 146, pressed by a spring 148, is clamped between the spout 14@ and member 136 and is moved n) against the spring pressure to permit uid passage by fluid pressure pumping.

1n use, with the pump and holder assembled with the container as illustrated in FIGURE 4, a depressive force applied to the outer end 1'14 of the lever 11d` to press the lever downwardly, causes the plunger 9@ to rise against the tension of the coil spring 132, permitting the oil collected in the valve sleeve 115 between the ball 55 and the captive ball 1218 to low upwardly through the passage 98 into and upwardly through the standard 70, into the member 136, against the ball 14d, unseating the ball 146 against the action of the spring 148, around the ball 146 and into the spout assembly 134 and out of the spout 1410. Release of the depressive force upon the lever 110 causes the plunger 90 to descend under the action of the coil spring 132 and the ball 146 to seat upon the member 136 under the action of the spring 148, resulting in the creation of a suction in the standard 70 and inducing the captive ball 128 to raise off its seat to thereby permit the oil to `tlow through the inlet opening 126 into the valve sleeve v116, through the passage 198 into the standard 7G.
